I have used the following set ups on my NSX's
Work Wheel's
17x8 F with 225 35 17 SO2 (no longer made)
18x10 R with 285 30 18 S02
SSR Integral's
17x8 F with 215 40 17 SO3
18x9 R with 275 35 18 SO3
Current on my 2002 silver NSX SSR Competitons
18x8 F with 225 25 18 SO3
18x9 R with 285 30 18 S03
I like the 17x8 18x9or10 combo the best but no one has the 225 35 18 size that also makes the 285 30 18 size. I do not like the 35 or 40's on rear with width more than 265 because it is to tall a side wall. The 215 40 17 has a bit taller side wall than the 285 30 18, altough the math says it should not.
Total tire hight is important to, so keep it in mind when you decide.
